Abstract

The invention discloses a hemolytic agent for a blood cell analyzing device. The hemolytic agent can decompose erythrocytes and blood platelets in blood. The invention also discloses a leukocyte classification kit. The leukocyte classification kit comprises the hemolytic agent, a dilute and an inhibitor. The agent provided by the invention is the assorted agent suitable for XFA9500 fully-automatic five-classification blood cell analyzer produced by Nanjing Perlong medical equipment limited company; the agent contains no dye, so that the agent is environment-friendly; by adopting the agent, lymphocyte, monocyte, neutrophile granulocyte, eosinophilic granulocyte and basophilic granulocyte can be directly detected; furthermore, the analysis method is fast and accurate.

Description

technical field [0001] The invention relates to the field of blood cell analysis, in particular to a hemolyzing agent for leukocyte classification and a kit thereof. Background technique [0002] Normal peripheral blood leukocytes are generally divided into five subgroups, namely lymphocytes (LYM), monocytes (MON), neutrophils (NEU), eosinophils (EOS) and basophils ( BASO). In the field of clinical analysis, accurate counting of different subgroups plays a very important role in diagnosis and research, and the changes in the content of each subgroup of white blood cells are used as important indicators for diagnosis and treatment in clinic. For example, viral infections can cause lymphocytosis, while parasitic infections and allergic diseases can cause eosinophilia. [0003] With the continuous development and improvement of the level of science and technology, hospitals currently use automatic blood cell analyzers to analyze white blood cells in peripheral blood. However...
